Deficiency or not?

born_it_allstarted grow question 4y ago

Hello, Im on 3rd week of growing (autoflower) and I saw some brown points on one of old leaves. Before i only gave root juice from biobizz and now I gave just one watering with 0,5ml/l of bio grow and 0,5ml/l calmag because I saw that brown points.It's some deficiency or not? Tks

Hard to tell by the photo, it’s blurred. That could be Ca deficiency, I’ve had something similar. Spots appeared on old leaves as well. CalMag helped.

KronicAquaponic

Lime green and droopy So she has been getting lighter the last couple weeks since the soil became too wet from being too deep in the aquaponic water, figure it’s ph related but I flushed her twice, each time ph came down, but didn’t seem to help, am I going the right direction or is it just N def now?

1st time grower - nute burn? Lockout? Potassium def? Light burn? HELP PLEASE Experiencing some deficiencies/light burn/heat stress. Says SSH likes hot/moist climate. Plants are planted in FFOF Soil, fed them 15oz of nutes yesterday. Using advanced nutrient systems, see above. Light is a SF1000 LED meant for a 2x2 tent. Would that burn them hanging at 20”?

Not sure why but she is showing either magnesium, calcium, or potassium deficiency. Do you agree? My PH is 6.3 this water, and was 6 the last sprinkle I gave her.

Possible pH issue.(15th photo) I've a few leaves which are not looking the best. Does this look like a pH problem or does anybody have other info? I have dropped a bit of lemon into this plant which is the only one with this issue which has not touched the other 2 plants under the same regime. Tx

Should I check only EC or PH is also important?I was told not to check for PH, add the nutes and check the EC, reach the level I want and that's it, is it right? I'm also checking the water coming out of the plants, they have EC 1+ above what I gave them. If I gave 1.5EC then it will have 2.5EC in the water coming out.
