Looks like your having a pH issue and then on top of that you’re having nutrient lock out. You should flush your medium and then re-amend with the correct pH water and then once that’s fixed then you can slowly add back the nutes.

your ph is off. flush the plant until your run off is at a 6.0. next let you plants dry out a bit, your in the starting phase of nutrient lock out.
when you start to feed add cal mag , last make sure you have air flow in your tent, a fan blowing on the wall of the tent. it is import for the air in the tent to move around, last raise your light about 2 inches all this combined will help improve your grow conditions.

Too much nitrogen and underwatering?Hey guys, can anyone tell me what they want (or have too much off?)
I think the big one has a bit too much nitrogen is my guess?
I also transplanted them today and yesterday so they had a bit less water as usual the past days. Could that be it as well?Leaves. Curl down

Overwatered cubes in hydro? Too close to the sun? or effect of having addHi All, I have issues with my first hydro grow - i effed up. I think i was too slow in the transfer over in the tank. Light is 200 PPFD, EC at 0.6, and barely added any nutes.

Curl and clawing,N-Toxicity?Flushing?Hello Growers!
Last week I gave around 1ml/L BioGrow in 600ml water. Now all leaves seem to me dark green. Some are disformed/wavey and show burned leave edges and slighty burned Tipps. Two of them seem to be handling the high nitrogen. But the third is curling/clawing. Wdyt?a year ago

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?
