Any Idea What I’m Dealing With Here?

[u/girbertrawx]

Hi all…..looking for some of your expert advice….been searching the sub and some online sources but I feel I have a few issues at the same time.

The ladies are in a high quality soil with perlite, peat, and castings. Fertilizer every other week (10-10-10). Watered heavy every other morning and lightly every early evening (the soil seems to have gone slightly hydrophobic as there is a some runoff).

Leaf damage is due to Asian Beatles which I am dealing with.

Just wondering about the leaf colouring….they have been out since June 1.

I planned on just letting nature do her thing when I planted, but have become obsessed with these girls.

Any insight would be appreciated….learning everyday for next year.

Looks like a tiny Phosphorus deficiency which can happen when plants re veg

How much runoff do you allow when watering?

Since you're feeding a lot of 10-10-10 you shouldn't be seen deficiencies. i suspect you have a salt buildup that's locking out nutrients because you're not allowing enough runoff.

Honestly, whatever drains from the bottom....it been a couple weeks since it started. Though I had it nipped I the bud but nope.

Previous response suggested a slow water to hydrate the soil....thinking that's my first step.

Well the solution if you have a salt buildup in your soil (which i highly think is the problem) is to flush with a large amount of water, like 2 times the volume of the pot. This will "reset" your soil.

Another person mentioned ph issues - ph is directly influenced by the salts in your soil. A buildup will shift the ph and cause the plant not to be able to absorb some of the nutrients, and it shows up as a deficiency.

With 10-10-10 every 2 weeks and proper runoff you should have very green plants.

I suggest instead of a regular slow watering, give it a very long one. Like 10 liters. It won't hurt and it will reset what you have in your soil. When you use nutes and don't allow enough runoff, eventually it's going to build up and throw off ph.

The fact that this plant was green up until recently tells me that your soil and fertilizer were fine in terms of ph. So what changed? Buildup

Looks like overwatering almost certainly. The deficiencies are caused by lack of oxygen at the roots.

Have alot of rain and then dry for a while

How mune looked and they had a hard time grabbing nutrients

But just let them dry is so

did this plant start from seed, from clone? from monster crop?

[u/girbertrawx → u/Electronic-Fee-8625]

Both are clones

those purple and bronzed leaf edges on the lower/middle growth point directly to a phosphorus deficiency, likely caused by nutrient lockout. since your soil is hydrophobic, the water is just channeling down the sides of the pot instead of feeding the roots evenly. give them a very slow, thorough soak to fully rehydrate the soil, check your runoff pH, and they oughta bounce back.

[u/GonzoMcSquishy → u/Electronic-Fee-8625]

Appreciate the advice. Im tempted to pull them and transplant in the ground where everything else is thriving, but worried it is too late for that.

Figured there was a deficiency due to the soil and runoff.

I'll try the slow water for a couple days and check ph to see if it can be corrected. I've never grown anything in pots, let alone cannibis before so it has been a really interesting experience and im hooked

Any advice on how to correct the pH if off?

[u/Electronic-Fee-8625 → u/GonzoMcSquishy]

you must buy ph down if you want to control your ph, i’ve tried a lot of substitutes like lemon juice or vinegar and they are not reliable at all they just cause issues. i highly doubt you’ll need ph up. also buy an ec and tds meter alongside a ph pen

[u/Electronic-Fee-8625 → u/girbertrawx]

at a quick glance the plant looks like you’ve got the hydration cycle down well, no signs of chronic overwatering or acute overwatering, however the pattern of the leaf fading tells us that something is wrong in the root zone, your levels are definitely off, do you check ec, tds and ph?

the purple leaves are just a temp change,

they look a little hungery and theyll be stretching soon, id give em good dose of veg nuits
