Hello, since yesterday my plant started developing...
lipz92started grow question 6y ago
Hello, since yesterday my plant started developing these weird marks on the leaves (day 20), this is my first grow, ppm around 220 and pH 5.5 to 6.5. Water temp 21°c and temp 28°c, any idea what might be causing this to my blue?

That is caused by your leaves laying on top of medium. Try to keep them off if you can. But nothing to be alarmed about. Everything you said is on point even 21c that is perfect water for hydro. Just be careful with nutrients cuz autos don't feed as much as a photoperiod. They use far less nutrients. I start autos at 1/8 strength and Max at around 1/3 strength of manufacturer recommendation.

Probably the Canna Rhizotonic , it’s not the first time that I see those weird marks with this product.
It can’t be over feeding at 220 ppm’s and pH seams correct. I would have think that the solution was supposed to be a lil bit cooler around 18°C in Hydro but I’m not an expert .

Balcony Auto Gelato with Yellow and Brown LeavesI'm growing this auto gelato in a balcony safe from rain fall and harsh wind, it's the 25th day and the bottom leaves and cotyledon are turning yellow and with some brown traces. I started to use minimum amount of "all in one" fert. Do you think it is overfertilization issue?

Leave Tips Yellow and Brown on New GrowthThe leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Nutrient & critter problems need 1-2weeks from harvest need adviceThe plant is a couple weeks of harvest but has some issues. (Some kind of nutrient lockout or deficiency can't tell what tho, pH is fine at about 5.8)
And I got these annoying critters that seem to live on the soil (but aren't touching the plant)
Any ideas on what to do ? :/

Some very little holes appear after feeding them, and maybe after I spray them with water. Could it be some light burn on the spots that some water bubbles had stay for long? Some nutrient burn? (I don't think so) I've searched for bugs and I think it is impossible, but no one knows when the little bastards want to show up... For now no signs of any kind of bugs... Maybe PH issues? I really don't know.Week 4

Leaves slowly dying. Nute burn? Heat Burn? Overwatering?Leaves are slowly dying on two of my plants. Starting to appear higher up at the tip. What could it be? PH, nute burn, too much light, overwatered? I may have overfed: 0,75mL Power Roots and Alga grow every two days since they were 10. Is it really bad?
